     This week's lab class, we are challenged to protect eggs from breaking when they fall from a high place. We tried four times. The first time, we dropped sand and straw at a distance of 1 meter without breaking them. The second and third times, we dropped them at a distance of 2 meters and they all broke when they popped out of the bowl. The fourth time, we added more sand and rubber to reinforce the bowl, and finally succeeded.  This is the first time This is the last time Let me know more about the F=ma. The more gradually the egg slows down, the smaller the force. We also learned the Newton’s Third Law——Forces come in equal pairs, which I learned before when I was in Chinese middle school. It was a good way to represent in the video which show on the lab class.  It also demonstrates the influence of buoyancy on the total weight. It is very interesting when see the physical experiment to understand these knowledge.

       In this week's lab class, we explored whether the direction of the wind would affect the round-trip time of riders. We used a fan and a rope with an iron ring to verify this issue. In the end, I found that the impact was not significant. I think this experiment is also very interesting, and we also discussed this week's reading. the author believes that students have the best learning outcomes when they exercise subjective initiative in their learning, especially when they participate in real-world problem-solving and inquiry based activities, which is consistent with the Next Generation Science Standard (NGSS). I think it will be very helpful for my future science teaching courses. I really like this classroom mode, we have enough time to validate our ideas, which is great. It also allowed us to learn the knowledge of dynamics very well.

         This week's lab class, our group conducted a verification to see if clothes made of different materials can affect the speed of children sliding down the slide. Speed is a variable, children are invariants, and clothes are also variables. We timed and collected each material three times, and I was responsible for calculating the average. Finally, it was found that Shimmer material clothes slide down the fastest, while Striped Pink material clothes slide down the slowest, so the material of the clothes does indeed affect the speed of sliding down the slide. I have taken such courses before, but I haven't really gone to experiment and verify like this lab class. I find it very interesting, and the feeling of teamwork can make the experiment more interesting and memorable. Different team members will provide different opinions and generate different ideas. This helps children develop teamwork and explore knowledge skills and interests among themselves. I t...
